Description

Technical Field

[0001] The utility model relates to the technical field of scraper and suction mud equipment, in particular to a novel scraper and suction mud device. Background Art

[0002] The sludge scraper is a kind of equipment used in sewage treatment plants, etc. Its main working principle is to drive the scraper blade to move forward and backward, left and right, up and down through the driving equipment. The scraper blade will scrape off the sludge at the bottom of the relevant area (such as the sludge settled at the bottom of the cooling pool, etc.), and then the matching sewage submersible pump will pump the sewage mixed with sludge to the outside of the relevant area to achieve the effect of sludge removal (such as pumping out the sewage containing sludge, transporting it to other places for treatment by sludge transport vehicles, or directly discharging the sludge into the sewage purification treatment pool at the side of the relevant area for treatment).

[0003] Although the existing scraper and suction machine has met the production needs to a certain extent, it is limited by the structure and still has the following technical problems that need to be improved. Specifically, when the staff controls the scraper blade to move downward, because the scraper blade is located below the water surface and the sludge, the staff cannot grasp the position of the scraper blade under the sludge in real time. In this way, it is possible that during the downward control, the lower end of the scraper blade contacts the bottom of the relevant area (such as the bottom of the cooling pool) and continues to move downward, causing the electric or hydraulic drive mechanism driving the scraper blade to be overloaded and damaged (there is also the problem of the lower end of the scraper blade being damaged due to excessive force). Taking the above factors into consideration, it is very necessary to provide a scraper and suction machine device that can have the functions of an ordinary scraper, can control the downward movement of the scraper blade, and can prompt the staff when the load is too large. Utility Model Content

[0004] In order to overcome the drawbacks of the existing scraper and suction machine due to structural limitations as shown in the background, the utility model provides a new type of scraper and suction machine device which can not only drive the scraper blade to move forward, backward, left and right to the working station under the joint action of relevant mechanisms, but also monitor the load of the scraper blade driving mechanism in real time when driving the scraper blade downward, and can promptly remind the staff when the load of the driving mechanism is too large, thereby effectively preventing the scraper blade driving mechanism and the scraper blade from being damaged due to excessive load.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A new type of scraper and suction mud machine device includes a motor reduction mechanism, an electric push rod, a gantry crane, a sewage submersible pump, and a mud scraper. It is characterized in that it also has a detection mechanism; the lower end of the body of the movable trolley of the gantry crane is installed with a support seat, the upper end of the motor reduction mechanism is installed at the lower end of the support seat, the upper end of the electric push rod is installed at the lower end of the rotating shaft of the motor reduction mechanism, the upper side end of the electric push rod is installed with a fixed plate, and the sewage submersible pump is installed at the side end of the fixed plate; the detection mechanism includes a pressure sensor and a detection circuit. The upper end of the pressure sensor is installed at the lower end of the electric push rod, and the force-bearing surface of the pressure sensor is located at the lower end, and the upper end of the mud scraper is installed at the lower end of the force-bearing surface of the pressure sensor; the detection circuit is installed in the electric control box.

[0007] Furthermore, when the lower end of the electric push rod is located at the bottom dead center, the lower height of the scraper is lower than the bottom of the sludge area.

[0008] Furthermore, the detection circuit includes an electrically connected relay, an alarm, a resistor, an adjustable resistor, and a transistor; the positive power input terminal of the relay is connected to the control power input terminal; one end of the adjustable resistor is connected to one end of the first resistor and one end of the second resistor; the other end of the second resistor is connected to the base of the transistor; the collector of the transistor is connected to the negative power input terminal of the relay; the other end of the first resistor is connected to the emitter of the transistor and the negative power input terminal of the buzzer; and the normally open contact terminal of the relay is connected to the positive power input terminal of the buzzer.

[0009] Furthermore, the other end of the adjustable resistor of the detection circuit is electrically connected to the signal output end of the pressure sensor.

[0010] Furthermore, the electric push rod can also be replaced by a hydraulic cylinder.

[0011] Compared with the prior art, the utility model has the following beneficial effects: (1) Under the joint action of relevant mechanisms, the staff of the utility model operates different buttons of the electric control box of the gantry crane to control the front and rear and left and right positions of the movable trolley. By controlling the rotation direction of the rotating shaft of the motor reduction mechanism and the upper or lower height position of the movable column of the electric push rod, the scraper can be controlled to move forward or backward, left or right, up or down to the relevant work station for operation. The sewage submersible pump can pump the water-containing sludge out of the relevant area in real time to achieve the effect of sludge removal (for example, pumping out the sewage containing sludge, transporting it to other places for treatment by a sludge transport vehicle, or directly discharging the sludge into the sewage purification treatment pool at the side end of the relevant area for treatment); (2) When the electric push rod pushes the scraper downward, the detection mechanism can monitor the load of the scraper drive mechanism in real time, and can promptly remind the staff when the load of the drive mechanism is too large, effectively preventing the scraper drive mechanism (electric push rod, etc.) and the scraper from being damaged due to excessive load.

The upper end of the pressure sensor A2 is installed at the lower end of the movable column of the electric push rod M1, and the force-bearing surface of the pressure sensor A2 is located at the lower end. The upper side of the upper connecting rod of the scraper blade 2 is vertically welded to the lower end of the force-bearing surface of the pressure sensor A2; the power module A1, the power switch, and the detection circuit 6 are installed in the electric control box 7 of the gantry crane.

[0016] Figure 1 , 2As shown in the figure, when the movable column of the electric push rod M1 is at the lower dead center, the lower part of the scraper blade 2 is lower than the bottom of the mud area. The detection circuit includes a relay K1, an alarm B1, resistors R1 and R2, an adjustable resistor RP1, and a transistor Q1 connected by wires through a circuit board. The positive power input end of the relay K1 is connected to the control power input end, one end of the adjustable resistor RP1 is connected to one end of the first resistor R1 and one end of the second resistor R2, the other end of the second resistor R2 is connected to the base of the transistor Q1, the collector of the transistor Q1 is connected to the negative power input end of the relay K1, the other end of the first resistor R1 is connected to the emitter of the transistor Q1 and the negative power input end of the buzzer B1, and the normally open contact end of the relay K1 is connected to the positive power input end of the buzzer B1. The other end of the adjustable resistor RP1 of the detection circuit is connected to the signal output end 3 of the pressure sensor A2 through a wire. The electric push rod M1 can also be replaced by a hydraulic cylinder. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply through wires, and the power output terminals 3 and 4 of the power module A1 are connected to the 1 and 2 pins of the pressure sensor A2 of the detection mechanism, the control power input terminal of the relay K1 and the emitter of the transistor Q1, and the power input terminals 1 and 2 of the power switches S and S1 are connected through wires. The power output terminals 3, 4 and 5, 6 of the power switches S and S1 are connected to the positive and negative and negative and positive and negative power input terminals of the motor reduction mechanism M and the electric push rod M1 through wires.

[0017] Figure 1 , 2As shown in the figure, the staff of the new type can control the gantry crane to move forward or backward along the guide rail, and control the 3 movable trolleys of the gantry crane to move left or right along the guide rail 32, thereby controlling the scraper 2 to move forward or backward along the guide rail, and move left or right along the 3 movable trolleys of the gantry crane to the operating point. When the scraper 2 is located at the operating point, it can also scrape the sludge at the corresponding position when it moves left or right, forward or backward. Specifically, after turning on the power switch of the sewage submersible pump 1, it actually pumps the water-containing sludge out of the relevant area in real time to achieve the effect of sludge removal, such as pumping out the sewage containing sludge, transporting it to other places for treatment by a sludge transport vehicle, or directly discharging the sludge to the sewage purification treatment pool at the side end of the relevant area for treatment. After the 220V power supply enters the power module A1, its 3 and 4 pins output a stable DC 24V power supply that enters the power switch S, S1 and the power input end of the detection mechanism. When the scraper 2 is located at the working station, when the staff turns the handle of the power switch S to the left or right, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch S are respectively turned on, so that the shaft of the motor reduction mechanism M will drive the scraper 2 to rotate clockwise or counterclockwise to a suitable angle for scraping mud. When the staff turns the handle of the power switch S1 to the left or right, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch S1 are respectively turned on, so that the active column of the electric push rod M1 will drive the scraper 2 to move up or down to a suitable height for scraping mud. In this new model, when the active column of the electric push rod M1 pushes the scraper 2 downward, the reverse force of the sludge on the scraper 2 will exert a force on the force-bearing surface of the pressure sensor A2. The greater the force of the scraper 2 contacting the sludge, the greater the force of the scraper 2 acting on the force-bearing surface of the pressure sensor A2, and the higher the voltage signal output by the 3rd pin of the pressure sensor A2, and vice versa. In actual situations, when the scraper 2 moves downward normally and the lower end does not touch the bottom of the pool, the reverse force on the pressure sensor A2 is relatively small, and the voltage signal output from the 3rd pin is relatively small. The voltage signal is divided by the adjustable resistor RP1 and the resistor R1. The resistor R2 reduces the voltage and limits the current. The voltage enters the base of the transistor Q1 below 0.7V, and the transistor Q1 is not turned on. The relay K1 will not be energized and the buzzer will not sound, indicating that the lower end of the scraper has not touched the bottom of the pool, etc. The staff can operate it to move downward normally. When the lower end of the scraper 2 touches the bottom of the pool when it moves downward, the reverse force on the pressure sensor A2 is relatively large, and the voltage signal output from the 3rd pin is relatively large. The voltage signal is divided by the adjustable resistor RP1 and the resistor R1. The resistor R2 reduces the voltage and limits the current, and the voltage signal enters the base of the transistor Q1, which is higher than 0.7V. The transistor Q1 is turned on, and the collector outputs a low level, which enters the negative power input terminal of the relay K1. The relay K1 will be energized to close its control power input terminal and the normally open contact terminal, and then the buzzer B1 will sound, indicating that the lower end of the scraper has touched the bottom of the pool, etc. The staff can stop operating the scraper to move downward, which effectively prevents the scraper drive mechanism (electric push rod, etc.) and the scraper from being damaged due to excessive load.

[0018] Figure 2 As shown, power module A1 is a finished product of AC 220V to DC 24V power module; motor reduction mechanism M is a finished product of coaxial motor gear reducer with a power of 1KW (AC motor gear reducer can also be used); electric push rod M1 is a finished product of reciprocating electric telescopic rod with a power of 150W, and its movable column movement stroke is 1 meter; the resistance values ​​of resistors R1 and R2 are 4.7K and 10K respectively; the relay K1 model is DC24V; buzzer B1 is a finished product of active continuous sound buzzer alarm with model FM24V; the resistance value of adjustable resistor RP1 is 100K (the technician adjusts the resistance value of adjustable resistor RP1 to a larger value and the voltage divider to a larger value. Then, when the force of the lower end of the scraper blade contacting the bottom of the pool is greater, the buzzer B1 will alarm, that is, the scraper blade detection threshold is set relatively large. The technician adjusts the resistance value of adjustable resistor RP1 to a smaller value and the voltage divider to a smaller value. Then, when the force of the lower end of the scraper blade contacting the bottom of the pool is smaller, the buzzer B1 will alarm, that is, the scraper blade detection threshold is set relatively small). Pressure sensor A2 is a waterproof high-precision pressure sensor product of model ZNLBM-IIX, which has two power input terminals and one signal output terminal.
